Although scientists have been working on technology that allows them to print biosensors to track patients’ vital signs, application of these sensors in the past has caused burns on the skin. A new innovation allows medical professionals to measure a patient’s blood oxygen saturation, electrical heart signals, and temperature from a biosensor that is safe for human skin. Created as a joint effort between the US and China, the innovation has the potential to allow medical staff to better monitor patients.
It could help medical personnel to see when a patient’s state is deteriorating before the signs are visually obvious. According to the primary researcher, Larry Cheng, the biosensor might work with another innovation that he helped develop, the wearable sweat monitor. If the two technologies are compatible, this could provide a more complete method of monitoring patients’ vital signs.
The researchers created a paint that can be applied to the skin that is similar to face masks that are peeled off the person’s face. The paint has nanoparticles to lower the temperature of the sensors. Currently, the team only has prototypes, but so far the technology has been successful. The prototypes are easy to remove without causing the patient any harm. At this point, the technology has only been used for a short period of time. Based on the early successes, the plan is to conduct trials where the sensors will be worn for longer periods of time.
